That's pretty cool. Is that the correct book?
Yes, If anyone who is a martial artist or wants to be a martial artist hasn't read this book, you should eagerly hunt it down. It discusses being a martial art, regardless of the art. It was the first book I ever read that made me ashamed I didn't train harder.
I've grown up incredibly since first reading this book, and I still go back and read it occasionally. Now the difference is that I'm inspired to train harder.
